The utility model relates to the technical field of wind shield processing, and disclose a kind of injection mold for wind shield processing, including base and fixed plate, model cavity is set up in base, the middle part of base is provided with through slot, the bottom end of fixed plate is provided with mould core, the top of fixed plate is provided with injection assembly, the inside of mould core is fixedly connected with several exhaust pipes, the middle part of mould core is provided with cavity, injection assembly includes four injection channels fixedly connected in the middle part of fixed plate, the top of four injection channels is fixedly connected with feeding pipe, the inner cavity middle part of feeding pipe is provided with conical flow guide block, injection material is injected into model cavity inner cavity from multiple positions by four injection channels simultaneously, effectively improve injection speed, ensure that material can be more evenly distributed in model cavity inner cavity simultaneously, gas generated in high temperature during mould use is discharged through multiple evenly arranged exhaust pipes, avoid that gas influences the product quality of wind shield.

The invention relates to the technical field of road construction, and provides a road maintenance crack repairing and flattening device which comprises a base, an inclined tamping assembly is arranged in the middle of the bottom end of the base and comprises a fixing plate fixedly arranged at the bottom end of the base, and a first driving chain wheel and two first rotating shafts are arranged on one side of the fixing plate; first connecting rods are arranged on the outer surfaces of the first rotating shafts, second connecting rods are arranged at the bottom end of the base, a third rotating shaft is arranged at the lower ends of the two first connecting rods, a fourth rotating shaft is arranged at the lower ends of the two second connecting rods, and mounting plates are arranged at one ends of the third rotating shaft and the fourth rotating shaft; arc-shaped plates capable of moving in an opening and closing mode are symmetrically arranged at the lower end of the mounting plate. According to the crack repairing and flattening device for road maintenance, the V-shaped structure capable of being adjusted to be opened and closed is matched with the inclined tamping assembly, multidirectional compaction and rapid surface leveling of a crack repairing material are achieved, and the compactness of a repairing layer and the flatness of a road surface are improved.

This utility model discloses an impact-type filling powder box, including a shell, within which a powder box body is installed. A first rotating shaft and two second rotating shafts located on either side of the first rotating shaft pass through the powder box body. A stirring paddle is sleeved on the first rotating shaft, and a slanted plate paddle is sleeved on the second rotating shaft. The powder box body is provided with a driving component for rotating the first and second rotating shafts. This utility model has the advantages of improving the stability of each filling and addressing the issues of low bulk ratio powders having poor flowability, small cavity size, and difficulty in filling.

The utility model relates to a shield tail brush, sponge is arranged in the shell, and the shell is filled up, the gasbag is connected to the sponge in the shell through the grease injection pipe, the fastening bolt penetrates the shell, and the upper and lower ends are respectively through the nut and resist the upper and lower ends of shell, and the oil is filled in the sponge through the gasbag and grease injection pipe, and the upper and lower ends of shell are resisted by screwing the nut, and the oil in the sponge is extruded and enters the steel wire brush lubrication between upper baffle and lower baffle, the device sets up the sponge in the shell, and the oil is transported in the sponge through the grease injection pipe by the gasbag, and the oil in the sponge is extruded and sent into the steel wire brush lubrication by the cooperation extrusion shell of fastening bolt and nut, and the manual operation mode is replaced more convenient and fast, and the gasbag can be taken down and add oil in the case of insufficient oil, guaranteeing the sufficiency of oil, not affecting normal construction.
